DETAILED DESCRIPTION OF THE INVENTION:

A screen 10, shown in phantom, is .in the path of a beam issuing from a lens of a light source 12. The light source 12 is positioned side by side with a lens of a photoresponsive device such as, for example, a phototube 13, mounted within a transmitter housing 14. A reflector 15 is positioned adjacent the pedestal 3. A bell housing 18 is provided at the rear of the typewriter 1.

In the system shown in FIG. 1, electrical energy or power enters the supporting base 4'via a power input 29. A starting switch 31 and a pilot light 34 are provided to actuate the system and to indicate its condition of energization, respectively. An electrical transformer 40, a control pack 42, an indicating pilot light 47 for the system, a two-way switch 56 and a cutout switch 59 for a line relay 61 are also provided.

A line meter and its pilot light 73 are shown in FIG. 1. A cutout switch 78 for a symbol relay 80 are also shown in FIG. 1. A pilot light 88 flashes to indicate the operation of a symbol meter 91.

A cutout switch 99 provides an ON and OFF condition for a word relay 101. Positioned directly beneath the space bar of the typewriter (not shown in the FIGS.) is a space bar switch 106. A word meter 118 has an accompanying pilot light 121. A space meter 128 records blank spaces and has a pilot light 131. A cutout switch 134'controls the space meter 128.

A pilot light 142 indicates the locking of a hyphen relay 145. Twin hyphen switches 166 and 169 are mechanically tied to each other by a mechanical linkage 170.

FIG. 2 illustrates the motion of a typewriter key 8 and shows the two positions of the key rotating about a pivot pin 9. The two positions of the screen 10 are its non-operating point and its effective interception of the light beam, indicated by a broken line in FIG. 1.

A clamping device 11, shown in FIGS. 2, 6 and 7, is affixed to the screen 10. As shown in FIGS. 3, 4 and 5, a bracket 16 has side cuts 17a and 17b for affixing the bracket to the bell housing 18 via screws 19a and 19b. The bracket 16 supports a platen switch 20, enclosed within a switch housing 21 and having an insulated envelope 172. The switch housing 21 is mounted on the bracket, 16 by means of a slotted portion 22 of the bracket, as shown in FIG. 4. The mounting of the switch housing 21 is determined by margin requirements on a typed sheet in the typewriter.

The platen carriage has a top edge 177, shown in FIGS. 3 and 4, and a bottom edge 180, shown in FIG. 3. A switch lever 178 is affixed to the platen carriage. The switch lever 178 has a slotted portion 179 which facilitates mounting of the lever on the movable portion of the typewriter l. A screw 181 secures the switch lever 178 in position.

In FIG. 3, three leads 201, 202 and 204 extend downward from the opening in the switch housing 21. The

lead 201 is connected to a plug 200b, intended to be inserted into a jack 200a mounted on the back of the supporting base 4. The lead 202 is similarly connected to a plug 203a, intended to be inserted into a jack 203b, The lead 204 is connected to a plug 205a, intended to t be inserted into a jack- 205b. The jacks 200a, 203b and 205bare connected to the leads v108, 58 and 111, respectively.

The screen is affixed to each of the 41 keys of the typewriter 1, except for the hyphen .key. As shown in FIG. 7, a clamp 11, comprising suitable flat spring metal, is affixed to the screen 10 via rivets 176a and 176b A clamp or snap-on device 24 is the same type of clamp or snap-on-device as the clamp 11. As shown in FIGS. 8 and 9, the clamp 24 is affixed to a plunger 26 by rivets 25a and 25b to deflect the linkage 170 of the twin hyphen switches 166 and 169.

terial is described in operation with reference to FIGS. 10A, 10B, as follows: When typing is commenced, the starting switch 31 is OFF and the twoway switch 56 is in its counterclockwise position, prior to the plugging of the connecting cord 28 into the power outlet 27 via the power input or plug 29. The starting switch 31 is then closed and the switch 56 is rotated in a clockwise .direction to its ultimate position. Actuation or energization of the system is indicated by the energization or illumination of the pilot light 34. A pilot light 47 indicates energization of the transformer 40 when the light is illuminated The initial circuit is described from the point of origin which is the power outlet 27, in order to simplify the description of the various sub-circuits. Thereafter, the other circuits are described as originating from two main leads 36'and 168. 7

Normally, when no typing key has been depressed, all 41 screens 1.0 are in their upper positions. When the starting switch 31 is in its ON position, the closing of said switch instantly energizes the control pack 42 and causes the armature of the relay 52 to be attracted by the magnetic field of the windings of said relay. However, current flow via the break contacts of the relay 52, since the flow of current is faster than the movement of the relay contacts, due to inertia.

This closes a circuit from the outlet 27, the connect-.

ing cord 28, the power inlet or plug 29, the lead 30, the starting switch 31, the lead 32, the main lead 36, the lead 49, the armature 52a of the relay 52, the stationary contact 51 of the relay 52, the lead 53, the movable contact or switch arm 54 of the switch 56, the stationary contact 55 of the switch 56, the lead 57, the lead 202, the plug 2030, the jack 203b, the lead 58, the switch 59, the lead 60, the line relay 61, the lead 62, the main lead 168 and the plug 29, back to the outlet 27.

The line relay 61 is thus energized momentarily and closes a circuit'from the main lead 36, the lead 63, the leads 64 and 65, the stationary contact '66 of the relay 61, .the armature 61a of the relay 61 the lead 68, the lead 69, the line meter 70, the lead 71, the shunt lead 72 of the, meter70, the pilot light 73 and the leads 74 and 75, to the main lead 168. The pilot light 73 is thus energized and flashes momentarily, and the line meter 70registers the first line before typing commences.

The counting system of the invention for printed ma- The typist has rotated the two-way switch 56, but the other circuits connected to the contacts of the relay 52 are open and nothing further occurs. When the typist depresses a key of the typewriter, the screen 10 of that key is moved into the path of the lightbeam between the housing 14 and the reflector 15. The relay 52 is then deenergized or released and its contacts are closed again. I

A circuit is closed from the main lead 36 through the lead 49, the armature 52a of the relay 52, the stationary contact 51 of the relay 52, the lead 53, the switch arm 54 of the switch 56, the stationary contact 76 of the switch 56, the lead 77, the switch 78, the lead 79, the symbol relay 80, the lead 81, to the main lead 168.

The symbol relay 80 is momentarily energized, and closes a circuit from the main lead 36, the lead 82, the armature 80a of the symbol relay 80, the stationary contact 84 of the relay 80, the lead 85, the lead wires 86 and 87, the pilot light 88,, the lead 89, the shunt lead 90 of the symbol meter 91, the symbol meter 91 and the leads 92, 93 and 94 to the main lead 168. The pilot light 88 is energized and flashes and the symbol meter 91 records thefirst stroke of a typewriter key.

The energizationof the symbol relay 80 also closes a circuit from the main lead 36, the lead 95, the armature 80b of the symbol relay 80, the stationary contact 97 of the symbol relay 80, the lead 98, the switch 99, thelead 100, the word relay'101, the leads 102 and 103, the stationary contact 104 of the space bar switch 106, the switch arm 105 of the space bar switch 106 and the leads 107 and 94 to the main lead 168. The word relay 101 is thusenergized. I

The word relay 101 locks in a circuit between the main lead 36, the lead 108, the jack200a, the plug 200b, the lead 201, the switch arm 109 of the switch 20, the stationary contact 110 of the switch 20, the lead 204, the plug 205a, the jack 205b, the leads llland 112, the stationary contact 1.13 of the word relay 101, the armature 101a of the word relay 101, the lead 115, the winding of the relay 101, the leads 102 and 103, the stationary contact 104 of the switch 106, the switch arm 105 of the switch 106 and the leads 107 and 94 to the main lead 168.

The energization of the word relay 101 also closes a Circuit between the main lead 36, the lead 1 16,, the lead 117, the word meter 118, the lead 119, the shunt leads and 122 of the word meter 118, the pilot light 121 connected between the shunt leads 102 andl12, the lead 123, the armature 101b of the word relay 101, the stationarycontact 125 of the. word relay 101 and the lead 126 to the main lead 168. The word meter 118 thereby records the first word, but is held energized by the word relay 101 in the initial registration until the completion of the word. v

The word relay 101 and the word meter 118 are deenergized or released by depressing thespacebar of the typewriter. This opens the switch 106 and opens the energizing circuit of the word relay 101. Theword relay 101 and the word meter 118 may also. be deenergized or released by shifting the typewriter carriage and tripping the trigger of the platen switch 20 thereby openin the locking circuit of said relay. I

The depression of the space bar of the typewriter also closes a circuit from the main lead 36, the lead 63, the lead 127, the space meter 128, the lead 129, the shunt leads 64, 130 and 132 of the space meter 128, the pilot light 131 connected between the leads 130 and 132,

arm 105 of the space bar switch 106 and the leads 107 and 94 to the main lead 168. The space meter 128 records the first space. The pilot light 131 is energized and flashes to indicate the operation of the space meter 128.

When a hypenated word is typed, the operation is performed by the twin hyphen switches 166 and 169. Since the hyphen ke'y has'no screen, the hyphen switch 166 can prevent a premature count of the hyphenated word, but cannot recort its stroke on the symbol meter 91. the twin hyphen switch 169 provides the operation,

because it performs simultaneously with the hyphen switch 166.

It is assumed that there is an incomplete portion of a typed word at the end of a line, a first circuit from the main lead 36 comprises a lead 137, the stationary contact 138 of the switch 166, the switch arm 139 of the switch 166, the leads 144 and 146, the pilot light 142, the shunt leads 141 and 143 of the hyphen relay 145, the lead 144, the hyphen relay 145, the pilot light 142 connected between the leads 141 and 143 and the leads 146 and 147 to .the main lead 168.

The hyphen relay 145 then locks in a circuit from the main lead 36, the lead 49, the armature 52b of the relay 52, the stationary contact 149 of the relay 52, the lead 150, the armature 145a of the hyphen relay 145, the contact 152 of the hyphen relay 145, the hyphen relay 145, the leads 146 and 147 to the main lead 168. When the hyphen relay 145 is locked,;neither the space bar nor the platen switch of the typewriter can release the word relay 101. Thisis apparent from the following circuits.

if the space bar of the typewriter is depressed, current is cut off at a circuit point 157 at the connection of the leads 102 and 103. However, this current, originating from the main lead 168, is replaced from said main lead by the hyphen relay 145. Since the hyphen relay 145 is locked, current from the main lead 168 flows through the lead 153, the stationary contact 154 of the hyphen relay 145, the armature 14517 of the hyphen relay 145, and-the lead 156 to the circuit point 157, thus holding the word relay 101 energized.

If the platen switch 20 is closed or tripped, the critical circuit point is 162, at the common connection of the leads 111, 112 and 161. When the platen switch 20 is opened, it cuts off current from the main lead'36. When the platen switch 20 is closed or tripped, the second line of typing is recorded, registered or counted in advance. A circuit is closed via the main lead 36,-the lead 108, the jack 2000, the plug 20012, the lead 201, the switch arm 109 of the platen switch 20, the stationary contact-183 of the platen switch 20, the lead 202, the plug 2030, the jack 20312, the lead 58, the switch 59, the lead 60, the line relay 61 and the lead 62 to the main lead 168. Another circuit which is closed comprises the main-lead 36, the lead 63, the lead 64, the lead 65, the stationary contact 66 of the line relay 61, the armature 61a of the line relay 61, the lead 68, the lead 69, the line meter 70, the lead 71 and the lead 75 to the main lead v168.The line meter 70 registers the second line of typing.

The hyphen relay 145 provides current from the main lead 36 through the lead 158, the stationary contact 159 of the hyphen-relay 145, the armature 8 1450 of the hyphen relay and the lead 161 to the critical junctionpoint 162.

The final required operation is the recording of the hyphen stroke by the symbol meter 91. When the hyphen key of the typewriter is depressed, the hypen switch 169 is operated and closes a circuit. The circuit is from the main lead 36 through the lead 163, the stationary contact 164 of the hyphen switch 169, the switch arm 165 of the hyphen switch '169, the lead 167, the lead 86, the lead 90, the symbol meter 91, the lead 92, the shunt leads 87 and 89 of the symbol meter 91, the pilot light 88 connected between the leads 87 and 89, the lead 93 and the lead 94 to the main lead 168.

While the invention has been described by means of a specific example and in a specific embodiment, I do not wishto be limited thereto, for obvious modifications will occur to those skilled in the art without departing from the spirit and scope of the invention.
